Claims (11)

1.,679/
2.CLAIMS 1. A medical probe, comprising: a shaft for navigation in a patient body, the shaft ending with a flexible section and a spring, followed by a rigid distal tip having one or more medical devices coupled thereto; a first deflection mechanism comprising a first wire attached to a first coupling point disposed in the flexible section of the shaft and a second wire attached to a second coupling point disposed in the flexible section of the shaft so that the first deflection mechanism deflects the flexible section relative to the shaft; and a second deflection mechanism comprising a third wire attached to a third coupling point disposed in the rigid distal tip and a fourth wire attached to a fourth coupling point disposed in a rigid distal tip so that the second deflection mechanism deflects the rigid distal tip independent of and relative to the flexible section by using the spring disposed between the flexible section and the rigid distal tip. 2. The medical probe according to claim 1, wherein the first wire is connected to the first coupling point opposite the second coupling point of the second wire.
3. The medical probe according to claim 2, and comprising a device external to the patient body, wherein the first and second wires extend between the flexible section and the device, and wherein the device is configured to deflect the flexible section relative to the shaft by applying a force to at least one of the first and second wires. 275,679/
4. The medical probe according to claim 3, wherein the force comprises a pulling force.
5. The medical probe according to claim 1, wherein the third wire is connected to a third coupling point opposite the fourth coupling point of the fourth wire.
6. The medical probe according to claim 5, and comprising a device external to the patient body, wherein the third and fourth wires extend between the rigid distal tip and the device, and wherein the device is configured to deflect the rigid distal tip relative to the flexible section by applying a force to at least one of the third and fourth wires.
7. The medical probe according to claim 6, wherein the force comprises a pulling force.
8. The medical probe according to claim 1, and comprising a handle, which is coupled to at least one of the first and second deflection mechanism, and which is configured to deflect at least one of the rigid distal tip and the flexible section, using, respectively, one or more of the first and second deflection mechanisms.
9. A method for producing a medical probe, the method comprising: assembling a shaft ending with a flexible section and a spring, followed by a rigid distal tip having one or more medical devices coupled thereto; and connecting, to the medical probe, first and second deflection mechanisms, wherein the first deflection mechanism deflects the flexible section relative to the shaft with a first wire attached to a first coupling point 275,679/ disposed in the flexible section and a second wire attached to a second coupling point disposed in the flexible section of the shaft, and the second deflection mechanism deflects the rigid distal tip relative to the flexible section with a third wire attached to a third coupling point disposed in the rigid distal tip and a fourth wire attached to a fourth coupling point disposed in the rigid distal tip so that the second deflection mechanism deflects the rigid distal tip independent of and relative to the flexible section by using the spring disposed between the flexible section and the rigid distal tip.
10. The method according to claim 9, wherein the first wire is connected to the first coupling point opposite the second coupling point of the second wire.
11. The method according to claim 9, wherein the third wire is connected to a third coupling point opposite the fourth coupling point of the fourth wire.
